Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer, Active Status):

The FCE17C37SN290 from Amphenol ICC represents the direct active equivalent to the obsolete FCC17C37SN290. Both connectors share identical mechanical and electrical specifications within the FCC/FCE17 series platform. The FCE17C37SN290 is RoHS compliant, addressing regulatory requirements for new designs. This part is the primary recommendation for direct replacement in applications where the original FCC17 series is specified.

TE Connectivity AMPLIMITE Series (Higher Current Rating):

The TE Connectivity AMPLIMITE HD-20 and HDP-20 series connectors (745189-7, 747315-1, 5745189-1, 5745189-7, 5747315-1) provide functional equivalence with enhanced electrical performance. These parts feature a 6A current rating compared to the 5A rating of the FCC17C37SN290, and operate across an extended temperature range of -55°C to 105°C. The voltage rating of 125V is lower than the original 200V specification. Selection of TE Connectivity parts is appropriate for applications where higher current capacity or extended temperature operation is required, provided the 125V voltage rating is acceptable.

NorComp 172 Series (Panel Mount Configuration):

The NorComp 172-037 series (172-037-283L001, 172-037-283L011, 172-037-283L021, 172-037-283L031) provides electrical equivalence with panel-mount mechanical configuration. These connectors feature ROHS3 compliance and extended operating temperature range (-50°C to 125°C). Selection of NorComp parts is appropriate for applications requiring panel-mount installation with through-hole termination. Flange feature variations (unthreaded, board side 4-40, mating side 4-40) must be matched to specific mechanical requirements.

RoHS Compliance Consideration:

For new designs subject to RoHS regulations, FCE17C37SN290, 172-037 series (all variants), 5745189-1, and 5745189-7 are compliant options. The original FCC17C37SN290 and TE Connectivity 745189-7 and 747315-1 are non-compliant or not applicable for RoHS status.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37SN290 be used as a direct replacement for FCC17C37SN290?

A: Yes. The FCE17C37SN290 is the active equivalent from Amphenol ICC. Both connectors share identical 37-position D-Sub receptacle configuration, female socket contacts, solder termination, through-hole mounting, and operating specifications. The FCE17C37SN290 is RoHS compliant, making it suitable for new designs.

Q: What is the difference between the TE Connectivity AMPLIMITE HD-20 and HDP-20 series?

A: Both series provide 37-position D-Sub receptacles with identical electrical and mechanical specifications. The primary difference is the dielectric material: HD-20 uses thermoplastic, while HDP-20 uses thermoplastic material. Both series feature 6A current rating and 125V voltage rating. Selection between series depends on specific application requirements and material compatibility.

Q: Why is the voltage rating lower on TE Connectivity parts (125V) compared to the original FCC17C37SN290 (200V)?

A: The TE Connectivity AMPLIMITE series is designed for different application requirements. The 125V rating is specified for these connector series. Applications requiring 200V operation must use Amphenol ICC or NorComp alternatives that maintain the original voltage specification.

Q: What is the significance of flange feature variations in the NorComp 172 series?

A: Flange feature variations determine mechanical mounting configuration. Housing/Shell (Unthreaded) provides basic panel mounting. Board Side (4-40) includes mounting holes on the board-facing side. Mating Side (4-40) includes mounting holes on the mating side. Selection depends on the specific mechanical installation requirements of the application.

Q: Are NorComp 172 series connectors compatible with applications designed for through-hole vertical mounting?

A: NorComp 172 series connectors support both panel mount and through-hole configurations. However, the panel-mount design may require different PCB layout considerations compared to the vertical through-hole mounting of the original FCC17C37SN290. Mechanical compatibility must be verified against specific application requirements.

Q: Which substitute part offers the highest current capacity?

A: TE Connectivity AMPLIMITE series connectors (745189-7, 747315-1, 5745189-1, 5745189-7, 5747315-1) provide 6A current rating, compared to 5A for the original FCC17C37SN290 and Amphenol ICC FCE17C37SN290. This 1A increase in current capacity may be beneficial for applications approaching the original 5A limit.

Q: What is the impact of shell material differences (Tin Plated vs. Nickel Plated)?

A: The original FCC17C37SN290 features steel shell with tin plating. NorComp 172 series uses steel shell with nickel plating. Both finishes provide corrosion protection and electrical conductivity. Selection depends on environmental exposure and specific application requirements for corrosion resistance.

Q: Can I use a substitute part with a higher operating temperature range?

A: Yes, provided the substitute part meets or exceeds all other electrical and mechanical specifications. NorComp 172 series and TE Connectivity AMPLIMITE series offer extended temperature ranges (-50°C to 125°C and -55°C to 105°C respectively) compared to the original -40°C to 85°C. Extended temperature capability does not negatively impact applications operating within the original temperature range.

Q: What inventory levels are available for each substitute part?

A: Current inventory levels are: FCE17C37SN290 (1087 pcs), 172-037-283L001 (1006 pcs), 172-037-283L011 (1121 pcs), 172-037-283L021 (1106 pcs), 172-037-283L031 (836 pcs), 745189-7 (2246 pcs), 747315-1 (832 pcs), 5745189-1 (1164 pcs), 5745189-7 (1761 pcs), 5747315-1 (1034 pcs). Inventory levels support procurement for both prototype and production quantities.
